A-segment

As of 2021, the A-segment category size spans from approximately 2.7 metres (110 in) to 3.7 metres (150 in).

Body styles for A-segment cars in Europe have historically nearly always been hatchbacks. But as crossovers gain popularity, new models have begun to shift to resemble crossovers. Examples of crossover city cars include Suzuki Ignis and Toyota Aygo X. Other body styles such as sedans have only a few models present in this segment because these shapes largely prove impractical at typical A-segment dimensions.

A-segment cars are traditionally offered with manual transmission as the sole transmission option. Beginning in the 2010s, automatic options are increasingly available. Some newer models most often utilize CVTs, while a small number of manufacturers also offer automated manual transmissions.

The engines of A-segment cars commonly range from 1.0 to 1.4 litres, either in inline-four or three configuration. Newer models may have turbocharged and/or hybrid engines with a particular emphasis on higher fuel efficiency.

In 2020, the ten best-selling A-segment cars in Europe were the Fiat Panda, Fiat 500, Toyota Aygo, Renault Twingo, Volkswagen Up!, Hyundai i10, Kia Picanto, Peugeot 108, Citroën C1 and Suzuki Ignis.

2019 - In 2019, sales of minicars were down 2% compared to a total market gain of 1% which means this segment now makes up 7.7% of the total European car market at 1.21 million sales, down from 8% in 2018. And with margins on minicars under pressure due to increased costs to comply with stricter safety and emissions standards, manufacturers are scaling back investments in to minicars or switching to an EV-only strategy.

In Italy, A-segment cars represented 16.4% of car sales in the first half of 2019.

2020 - European sales of minicars were down by a third in 2020, which translates to nearly 400,000 fewer sales and means the segment loses market share as the overall market is down 24%. As a result, this segment now makes up 6.8% of the total European car market, down from 7.7% last year. And their share is expected to shrink further in coming years, as manufacturers are pulling out of this segment or switching their models to EV-only. This is a result of increasing costs to comply with stricter safety and especially emissions standards, which makes minicars nearly unprofitable, especially considering that for most models from European brands this is the only market.

In the United States, minicar segment cars represented 0.5% of the market share.

In 2020 the highest selling minicar segment cars in the U.S. were the Chevrolet Spark, Mitsubishi Mirage and Mini Cooper.

In India, historically the A-segment cars had the highest sales. Sales have been in decline in recent years, falling from 70,000 sales per month in 2014 to 47,000 sales per month in 2016.

As of 2019, several A-segment cars had successes outside Europe, such as Hyundai Grand i10, Honda Brio, Kia Picanto, Tata Tiago, Toyota Wigo, Suzuki Celerio, Suzuki Wagon R, Suzuki/Maruti Alto, Ford Figo, Smart ForTwo, Citroën C1, Peugeot 108, and modern Fiat 500.
